intermediate step load high efficiency screw chillers . The chillers together with the Chilled Water and Condenser Water Pumps are positioned in an enclosed plant room on Level 4 of the development .
The chillers are served by a number of open-circuit cooling towers which are mounted in an open plant area situated at the back of the site so as to avoid noise pollution to the Hotel and residential blocks .
Each chiller is interconnected with one or more cooling towers by means of galvanised steel condenser water piping and condenser water pumps including standby pumps . Chilled water is circulated to each building by means of insulated medium black steel ring main piping and chilled water pumps including standby pumps . At various plantrooms , there is a dedicated heat exchanger and a tertiary chilled water pump station which services each building . This includes each residential block , Hotel block and retail .
Three identically sized pumps with variable speed controllers , two run and one standby , are provided for each . Chilled water shall then be circulated within its own loop per building / user thereby eliminating the risk of a water leak affecting the entire main plant and avoiding unnecessary pumping power losses .
An energy meter is installed in the primary leaving chilled water piping to record the amount of chilled water supplied to the building by the chillers and to track the thermal energy used by the plant .” CLA

Being less than a kilometre from the shoreline , a watercooled chilled water system was selected for its efficiency and longevity as there are less components exposed to the elements when compared to air-cooled systems . |
